Intranasal Dexmedetomidine vs Oral Midazolam for Premedication in Pediatric Surgery
Comparison of Intranasal Dexmedetomidine and Oral Midazolam for Premedication in Pediatric Patients Undergoing Elective Inguinal and Urological Surgery: A Prospective, Randomized, Double-Blind, Controlled Trial
This study aims to compare the effects of intranasal dexmedetomidine and oral midazolam as premedication in pediatric patients undergoing elective inguinal and urological surgery under general anesthesia.
Premedication plays a critical role in reducing preoperative anxiety, facilitating parent-child separation, and improving cooperation during anesthesia induction in pediatric patients. While oral midazolam is widely used, it has several limitations, including variable bioavailability and the risk of paradoxical reactions. Intranasal dexmedetomidine has emerged as a promising alternative due to its sedative, anxiolytic, and minimal respiratory depressant effects.
In this prospective, randomized, double-blind, controlled study, patients aged 2-10 years will be assigned to receive either intranasal dexmedetomidine or oral midazolam prior to anesthesia induction. The primary outcome is the proportion of patients achieving adequate sedation at induction, defined as a Ramsay Sedation Score (RSS) ≥2.
Secondary outcomes include perioperative hemodynamic stability, parent-child separation anxiety, mask acceptance during induction, postoperative emergence agitation, recovery time, and the need for rescue sedation.

Szczegółowy opis
This prospective, randomized, double-blind, controlled clinical trial aims to compare intranasal dexmedetomidine and oral midazolam as premedication in pediatric patients undergoing elective inguinal and urological surgery under general anesthesia.
Premedication is essential in pediatric anesthesia to reduce preoperative anxiety, facilitate parent-child separation, and improve cooperation during anesthesia induction. Oral midazolam is widely used but has limitations such as variable bioavailability and potential adverse behavioral effects. Dexmedetomidine, a selective α2-adrenoreceptor agonist, has emerged as an alternative due to its sedative, anxiolytic, and minimal respiratory depressant effects.
Eligible pediatric patients will be prospectively enrolled and randomly assigned to receive either intranasal dexmedetomidine or oral midazolam. A double-blind design will be maintained by administering both oral and intranasal preparations in each group. Premedication will be administered prior to anesthesia induction, and perioperative clinical parameters will be recorded.
This study is expected to provide clinically relevant evidence regarding the effectiveness and safety of intranasal dexmedetomidine compared to oral midazolam, potentially contributing to improved premedication strategies in pediatric anesthesia.

Aktywny komparator: Midazolam Group
Participants in this group will receive oral midazolam at a dose of 0.5 mg/kg (maximum 15 mg) as premedication 30 minutes prior to anesthesia induction, along with intranasal placebo to maintain blinding.
This approach ensures consistent administration routes across study groups.

Parent-child separation anxiety score
Ramy czasowe: At parent-child separation before anesthesia induction

Parent-child separation anxiety will be assessed using the Parental Separation Anxiety Scale (PSAS). The scale ranges from 1 to 4, where 1 indicates "calm/easy separation" and 4 indicates "crying/extreme difficulty in separation." Higher scores represent worse outcomes (higher levels of anxiety). A score of >2 is defined as significant separation anxiety. Unit of Measure: Units on a scale |
